When driving through city traffic basically stop and go the brake pedal gets very hard and the car does not stop as smooth or almost not at all. It gets very dangerous.

Braking is diminished when vehicle is moving at slow speed and brake pedal is pressed. The vehicle brake assist engages by pulsing, increasing the braking distance by not stopping the vehicle no matter how hard the brake pedal is pushed. Emergency brake is used to prevent vehicle from colliding. This may be related to NHTSA 19V645

I purchased my vehicle after the recall 19V-645 regarding the brake pump was issued. My vehicle was a part of that safety recall, and the module was reprogrammed in September 2019 (N192268490-01). The pump has not been previously replaced according to service records. I purchased my vehicle from a dealership in April 2021. I recently (late 2023) started having issues with my brakes, having increased brake pedal effort, a hard brake pedal, and increased stopping distance. I have had the brake assist alert come on several times. The issue happens more frequently at lower speeds. My park assist alert also comes on regularly when applying the brakes. I have taken my vehicle to GM several times regarding the park assist issues, but they have only cleared the computer codes and cannot figure out why they keep coming back, as there is no detectable issues with the system. I have also brought my vehicle in due to the adaptive cruise control, as it has also caused issues while using it. It will often apply brakes if it detects a vehicle in another lane while driving, causing the vehicle to -??slam-?? on the brakes going at high rates of speed (I.e. driving on the interstate at 80 mph) and has nearly caused accidents, as the vehicle becomes hard to control, and the risk of following vehicles not having the reaction time to avoid a rear-end collision is increased. My particular vehicle does not have an option to switch between regular cruise control, and adaptive cruise control. After talking with GM, they informed me the only way to -??fix-?? the issue is to completely replace the module with an updated module that allows the option to turn off the adaptive cruise control, which is quite costly to the consumer. My vehicle is currently at a GM service department, and has been diagnosed that the brake pump has failed, and needs replaced. They are claiming that it is not covered under the recall. It is not covered under GM-??s extended warranty due to mileage restrictions.

I have a 2015 Chevrolet Suburban that had an issue with the brakes not wanting to stop the vehicle at slow speeds. Several times when we pulled into our garage or a parking space the vehicle would want to glide instead of stopping. I've had several parts replaced and am now hoping the problem is fixed. just picked the car up today from repair shop.

The vehicle component of concern is the braking system. The brake pedal has to be pressed at an unusual rate of pressure to engage the brake system. More concerning is, on several occasions the brakes seem to fail, initiating the ABS system while in fast food lines. This has also occurred while backing up causing the pedal to be jammed to the floor to stop the vehicle. The excessive need for pressure while braking was supposed to be fixed in 2021 by a "simple" recall that simply updated the computer. I had this recall performed, but still have the same braking issues in my 2015 Chevrolet Suburban. I feel that this is a very serious concern and should be addressed. The difference is truly night and day between my wife's vehicle and mine. The braking issue comes with no warnings or alarms. I have had my brakes checked on several occasions to confirm normal brake wear and longevity.

After about 10 min idling vehicle, noticed -??service brake assist-?? message. When it was time to pull out onto road, the vehicle did not brake as expected. I had to push much harder on brake pedal, and heard clicking noise. I was in front of the middle school and because the vehicle was going very slow I was able to stop, but could have had an accident if the speed was higher or if I wasn-??t strong enough to push pedal harder. This happened today 2/25/2022 and the outside temp is 3F. This seems just like the recall n192268490 on the consumer reports website, but the dealer says this vehicle is not affected even though it is the same year and model name.

My wife drives a 2015 Chevrolet Suburban LTZ. The brake pedal would vibrate when pressed going at slow speed or when reversing for weeks leading up to the break failure; however, no service message would appear on the dashboard instrument panel. On December 17, 2021 my wife was driving when someone in another vehicle crossed the highway right in front of her, when she pressed the brakes, they were very hard to press and the 2015 Suburban was not able to stop. Fortunately, she barely missed colliding with the other vehicle. She was able to coast to a slow speed and pull over into the grass and glide to a stop because the brakes would not work. This was the first time that a "Service Brake Assist" message appeared on the dashboard instrument panel. We had the Suburban towed to the nearest Chevrolet dealership. In researching the problem, there has been a recall issued for this type of failure of the brakes for 2015-2018 Chevrolet Suburbans; however, there is no recall for our Suburban according to the VIN #. Failure of the braking system on a vehicle is very dangerous and can result in injury or death. I strongly believe our vehicle, and other vehicles like ours, should be added to the recall list as soon as possible before someone gets seriously injured or dies due to not being able to stop and crashing into another vehicle, person, or object. The Chevrolet dealership says that since our vehicle is not on the recall list, we are responsible for the charges to fix it; however, I believe that the manufacturer (Chevrolet) should pay for the expenses since this seems to be a defect of the parts that are failing, especially since the Suburban is only 6 years old and has less than 100,000 miles.

The Service Trailer Brake System keeps popping up. Keeps dinging off and on whether you push the dismiss button or not. When this is on I question if the electrical brakes will work when I tow our camper. It is very distracting while driving. Safety Concern for sure!

The system that is failing is on my Suburban is the Trailer Break System, yes it is available for inspection. The continuous alert is distracting to the point of the vehicle being un-drivable and without the trailer break system functioning properly it puts people in danger due to not being able to safely stop while towing. The dealership said they were unable to reproduce the code. The vehicle has not been inspected by anyone except the dealership. Yes, both a visual and audible alert pops up continuously with a loud -??ding-?? and a -??Service Trailer Break System-?? warning.

The recall issues are still happening. It flashes service brake assist. When at low speeds or in reverse the brake pedal will suddenly become very hard to use and it is very unpredictable. Pedestrians, children and other vehicles have been at risk. We have been calling Chevy for nearly a year with the problem. They kept telling us it was fixed. We called again today and they said because our vehicle has 8k too many miles on it, there is a recall service that could have been done before but now we have to pay for it when we have been calling about it often.
